If we want to view the status of all our interfaces on a router we can use the show ip interfaces brief command. This will display the following:
Interface IP-Address OK? Method Status Protocol
Ethernet0 192.168.1.1 YES manual up up
Serial1/0 unassigned YES unset administratively down down
Serial2/0 10.10.1.1 YES manual up up
Serial2/1 192.168.2.1 YES manual up up
As we can see we have a summary of each interface and a handy first step for troubleshooting.
Oopsies this a double post, my mistake…
